DL580 G1 "Unsupported Processor Detected" Error

I have a DL580 G1 with four 900/100 MHz / 2MB Cache CPU's. It was working fine, but was offline and unpowered for several months. Upon restart, the machine begins the BIOS POST, recognizes the four processors and then hangs with the error, "Unsupported Processor Detected", System Halted. Everyone I have spoken to that had a clue about this issue has recommended that I upgrade the BIOS, but I can't very well upgrade the BIOS if the machine won't even boot. What are my options? What do you recommend be done to fix the problem? Are there any jumpers or DIP switches to check? Special keys to press during boot-up? Please advise.
